WooCommerce Memberships

I really really really would like to choose to change the end date for an existing group/plan. I get the idea for the existing system, that the existing members will keep the ending date they signed up for even if you change it for new members. But I need to change the end date for hundreds existing plan members now and have to do this individually for each and every member.
So please please please create an oportunity to change for the whole group, or a segment between joining dates, or whatever solution you can code that will solve this issue <3
